And most of my students have them. I don't care if they do homework at the desk working as long as they get up and help folks cheerfully when they need to. They plug them in, work on their stuff, don't save to my computers, take them away again--it's brilliant, and means they can essentially work on their stuff at whatever computer without a fuss.

I mean, yeah, still standing in line for a comp, but a lot less of a pain than carrying around disks and whatnot.
